2700k is the color temp, not any amount of light output. How many watts of cfl are you running in there with the 4 lights? With cfl you gotta put the lights all around the plant, not just above it like with HID lighting. I would transplant then now if I were you. The further along in the flowering cycle, the more likely you will stress with a transplant. I usually don't like to transplant past the first week or two of flower. Also, transplanting from a ceramic container can be a bitch. I would suggest using cheapo plastic nursery containers instead. I just started using some nice extra deep square containers myself.Thanks there is 4 bulbs in there just can't see them each puts out 2700k of light I know there stretched didn't put my light close enought when they were young there totally organic not used any newts and used a quality organic soil will be transfer them into bigger pots was just worried about stressing them
